From beac82904a870b220d45b883e493b869d8d0dce5 Mon Sep 17 00:00:00 2001 From: Stanimir Varbanov Date: Thu, 17 Jan 2019 07:43:31 -0200 Subject: [PATCH] media: venus: make decoder compliant with stateful codec API This refactors code for start/stop streaming vb2 operations and adds a state machine handling similar to the one in stateful codec API documentation. One major change is that now the HFI session is started on STREAMON(OUTPUT) and stopped on REQBUF(OUTPUT,count=0), during that time STREAMOFF(CAP,OUT) just flush buffers but doesn't stop the session. The other major change is that now the capture and output queues are completely separated.
